I'm more interested in well tolerated selective MAO-B inhibitors as they have the potential to make PEA a poor man's amphetamine while addressing some of amphetamine's inherent toxicity. Without digging out my research laptop it appears that most well known herbal MAOI's are either MAO-A selective or non-selective (such as curcumin). Also, please for the love of whatever you hold holy don't go for something that's known or likely to be a irreversible inhibitor of MAO-A. The last thing anyone wants is to sink their teeth into a block of cheese and have their heart explode.
